Bathtub

We don’t have a tub in our home, only a shower so I’ve been looking into different bath tubs that my LO will be able to use as he grows. We currently only have an infant one and he’s starting to grow out of it. He will be 6 months old and he’s able to sit by himself. I came across the gymax folding bathtub from Walmart. Has anyone used this tub? Did you like it or dislike it? For anyone else that only has a shower what infant/toddler tub did you use?
